PLASMA POLYMERIZATION OF ACETYLENE IN RADIO-FREQUENCY GLOW DISCHARGE
本文讨论了在无极电容耦合辉光放电等离子体聚合装置内的乙炔等离子体聚合的聚合规律、聚合机理、聚合产物的结构及聚合产物在反应器内的分布等何题。实验表明,聚合产物的淀积量随放电时何线性增长,放电功率对聚合产物的淀积速率.玻积分布和产物结构都影响不大。影响聚合物淀积速率的主要因素是单体和载气(Ar,He,N2,H2)的分压。纯单体的聚合速率有单体的压力成正比.添加载气(Ar,N2,He)能提高聚合速率。但以氢气作载气时,聚合速率及而下降,这可能是由于氢气有单体发生了氧化反应,单体饱和度增加所致 ...
